LINOTYPE-MAQHINE ATTACH ENT.

SPECIFICATIONforming part of Letters Patent no. 758,284. dated April 26, 1904. Application filed my 4; 1903. were. 155,531. in. model.)

.To (all whom it Huey concern:

Be it known that I, Pa rnionS -inn; a citizen of the United Stat-cs residing at )hicago, in"

the county of (loo 2 and State of Illinois, have invented a new. and useful Improvement in Linotype-Machine Attachments, of which the following is a specification.-

My invention relates particularly to the actuating means of the asseriibler-block,some' times termed assembling-elevator, of linotype-machines of the general construction'set forth in hlergenthalers patent, No. 557,000,

dated March 2 1896. 4

lily. primary object is to providc'knee-oo,

crated mechanism forraising the assemblerblock at which the composition takes place, so that itwill be unnecessary for the, operator .to emplog his hands for such purpose.

My invention is illustrated in its preferred embodiments in the accompanying drawings, in which j Figure 1 represents a perspective View of a portion of a .linotype-machine provided with my improvement, and Fig. 2 a sectional view the composition proceeds; C, a link connected withthemomberB in the usual manner and through the medium whereof said member is elevated; U, the usual rock-sliaft oni-nailed in suitable bearings 11 and equipped atone end with a handle and at the opposite end with an arm'C pivotally connected at its rear-end with the lower end of the link l; and 1.), my im proved knee-actuated device connected with the arm C.

in the form shown in Fig. 1 the'deviee 1) comprises a member 6, adjustahl v clamped u pen the arm (3 ,21 link I) of adjustable length, and a yoke/or curved knee-engaging member I); 'l. he member 5 comprises a bar having a long slot which receives the arm G and a clamping-screw c. The lower end of the memher is slotted to receive the link 1), with which it is connected by a pivot'u'. .ilie link 1/ comprisesan upper internally-threaded portion 47, a lower internallytlu-eadcd member 41 and a right and left threaded connectingerod (1 The portion 'rl' represent-portions :of a. link corresponding represents a yoke corresponding with the yoke 5 In this construction the transverse pivotal connection between the link and yoke is dispensed with and the yoke has vertical swivel connection with the link. 'lheyokeis of convex cross-section at.v its lower surface, which permits it to rock upon the knee or thigh of the operator.

In Fig. 1 the device is represented in the position it would occupy were it resting upon the'operatofis knee. p

1n attaching the device to the arm U" the clamp?) is set so as to incline rcarwardly and upwardly. sl'hen it is desired to elevate the assembler-block, which heretofore hasv been accomplished by d'epressingthe hundlei the knee of the opcratoris raiserL'lii'ting the arm 0" through the mediu m or the link 6' and clamp 7. As the arm C rotates about its shaft f the clamp is brought to a vertical position, straightening thcjoiut at its lower end and increasing the distance between the knee and the arm C". Thus for a given movement of the knee a. greater movement of the arm U is eil'ected. Either one of the stops f" mar serve in the operation, according -to the convenience of the operator, his stature, eke. Moreover, a certain slight movement between the link and yoke may take place as thejoiut at c straighter, reducing the rocking movement of the yoke upon the knee.

In themodification of Fig. the yoke is of acouliguration which permitsit to rock freei v upon the knee, and its swivel connection with l the link permits the yoke to accommodate itself to theleg', regardless of the angle which the latter occupies with reference to the lront of the machine.

The clamp of the device may be adjusted forwardly or backwardly and s ngularly to accommodatethe device to persons of diflerent Changes in details of v v templated, so that no. undue limitationshould be. understood from the foregoing detailed description. 'What I regard as new, by Letters Patent, 'is

1. The combinationand desire to secure with the assembler block, and the upwardlyswingingrock arm construction are con-' engaging member.
